Each loop has a push button next to the loop return that gives you the option to turn a standard loop into a flip/flop loop.
Instantly switch between any selected loops while adding other loops on top. Its great if there are effects on your board that you never stack like multiple delays, or drive units.
By using the QMX returns as instrument inputs you can easily and quietly switch between your favourite guitars

We know better than anyone how important your tone is, which is why we use the best quality gold contact relays to handle the switching. We never put your signal through unreliable 3PDT foot switches.
